FLASK Filed Nov. 2, 1929 INVENTOR. James 5': Hin s Patented June 14, 1932 JAMES F. HINES, OF LAKEWOOD, OHIO FLASK Applicationfiled November 2, 1929.

The present invention relates, as indicated.

to flasks, and more particularly to sand'retaining means for the cope sections of flasks. The primary object of the invention is to provide an improved cope section. A further object of the invention is to provide improved sand strip means. A still further object of the invention is to provide improved means for operating the sand strips. Further bjects of the invention will appear as the description proceeds. To the accomplishment of the foregoing and related ends, said invention. then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however. but one 20 of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing: Fig. 1 is an inverted perspective view of a cope section having my improved sand strip 25 means mounted thereon; Fig. 2 is a broken plan view of a portion of Fig. 1, the view being inverted from the position of use; Fig. 3 is a section taken substantially upon the line 33 of Fig. 2: and Fig. 4 is a sectional view taken substantially at right angles to the plane of Fig. 3.

Referring more particularly to the drawing. it will be seen that I have provided a cope section indicated generally at and 35 comprising side walls 11 and end walls 12. Upon the lower edge of each of the side walls 11 there is mounted a sand strip 13, and upon the lower edge of each of the end walls 12 there is mounted a sand strip 14. As is clearly shown, the strips 13 are provided with diagonally extending slots 15 therein. while the strips 14 are provided with corresponding slots 16'. .said slots receiving pins 17 upon the walls 11 and 12, which pins act to retain the strips 13 and 14 upon the walls 11 and 12, and to guide said strips in their movements. Each of the strips 13 is formed at its one end with a projection 18, while each of the strips 14 is provided at its end adjacent said 553 end of each strip 13 with a corresponding Serial No. 404,228.

projection 19. The projections 18 are formed with notches 20 in which engage lugs 21 on the projections 19, whereby said adjacent strips 13 and 14 are interengaged; Each of the projections 18 is likewiseformed with a second notch 22 with which mates a notch 23 in the corresponding projection 19, said notches 22 and 23 cooperating toform asocket. I

I have provided novel means for moving the strips 13 and 14. Such means comprises a housing 24 secured to the cope section immediately above the projections 18 and 19 on the strips 13 and 14. One wall of the housing 24 is provided with an aperture 25 with which is aligned an aperture 26 in the opposite wall of said housing, said aperture 26 being threaded for cooperation with the threaded portion 27 of a bolt 28 extending through said apertures 25 and 26. A lock 7 nut 29 is preferably threaded onto the projecting end of the bolt 28 to hold'the same in place. A lever 30 is pivotally mounted upon said bolt 28 and has its one arm 31 extending downwardly and outwardly through the open lower end 32 of the'housing 24, the extremity of saidarm 31 being entered in the corresponding socket 22-23 formed in the projections 18 and 19. The opposite arm 33 of the lever 30 extends upwardly within the housing 24 and is provided with alaterally extending pin 34 which is received in a slot 35 in one arm 36 ofa bell-crank lever 37. Said lever 37 is provided with alaterally extending pin 38 received in an aperture 39 in the wall of the housing 24in which is formed the aperture 25. and the opposite arm 40 of said lever 37 extends outwardly of the housing 24 through a slot 41 in the outer wall 42 of said housing.

As will be obvious. if the arm 40 of the lever-37 is moved downwardly in its slot 41 when the cope is upright). the strips 13 and 14 in the socket of which the lever end 31 is received will be moved inwardly into sand Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be empioyed.

I therefore particularly point out and distinctly claim as my invention:

1. In combination with a flask section sand retaining mechanism mounted on said section and comprising sand strips mounted on certain of the walls of said section, means for retaining said strips on said walls and for guiding the movement of said strips, and means for moving said strips into and out of sand-retaining position, said last-named means comprising a housing mounted on said flask section, a lever mounted in said housing and projecting outwardly therefrom into cooperative relation with onerof said sand strips, and a second lever projecting out- Wardly from said housing operative connection with flask section, a lever pivoted in said housing and projecting outwardly therefrom into co operative relation with one of said sand strips, and a second lever pivoted in said housing and projecting outwardly therefrom, said second lever being formed with a slot receiving a pin on said first lever whereby movementof said second lever is translated throulgh said first lever to said sand strip 3. n combination with a flask section, sand retaining mechanism mounted on said section and comprising sand strips mounted on certain of the walls of said section, means for retaining said strips on said walls and for guiding the movementof said strips, and

means for moving said strips into and out of sand-retaining position, said last-named means comprising a housing mounted on said flask section, a lever pivoted in said housing and having its one arm projecting outwardly from said housing and into cooperative relation with one of said strips, a pin on the other arm of said lever, a bell-crank lever pivoted in said housing at a point intermedi- 1 ate said pin and the pivotal point of said first lever, said bell-crank lever having its one arm extending outwardly from said housing and havingits other arm formed with a slot receiving said pin.

and having an said first leverwhereby movement of said second lever is 4. In combination with a flask section, sand retaining mechanism mounted on said section and comprising sand strips mounted on certain of the walls of said section, means for retaining said strips on said walls and for guiding the movement of said strips, and means for moving said strips into and out of sand-retaining position, said last-named means comprising a housing mounted on said flask section, a lever pivoted in said housing and having its one arm projecting outwardly from said housing and into cooperative relation with one of said strips, a pin on the other arm of said lever, a bell-crank lever pivoted in said housing at a point intermediate said pin and the pivotal point of said first lever, said bell-crank lever having its one arm enclosed in said housing and formed with a slot receiving said pin. a
